This project consisted of upgrading 49 locations of the existing 48” and 54” water main of the West Pipeline. Included in the project was video inspecting 6 miles of the pipeline, installation of new 4” and 6” ARV’s , 2” blow-offs, 8” Butterfly Gate Valves, and Cathodic Protection test stations. The project was extremely time critical as the pipeline could only be shutdown for 35 days. The shutdown work was completed ahead of schedule.

This pilot project for the cities drainage issues involved the installation of 600 LF of trench drain, demo, form and pour of 3 new driveways, 130’ of Curb and Gutter Restoration, and 2,500 SF of street restoration. This project was completed ahead of schedule with minimal impact to a very civically active neighborhood.

This project consisted of working on a 3 mile stretch of the East Pipeline – a treated water transmission pipeline. The work includedvideo inspecting the 3 miles of pipeline first, thenRemoval and installationof(5) buried 1” ARV’s, Installation of (2) 16” in-line flow meters, and the installation of a 20” & 30” Butterfly Valve withelectric actuator’s. The project finished ahead of schedule.

This project consisted of rehabbing a 20’ section of a buried 78” Concrete Pipe under the Alamitos Creek. The work included dewatering the pipeline, fabricating and welding in an interior stainless-steel lining for the pipe, pressure grouting between the new lining and the existing buried 78” pipe, epoxy coat the new section of stainless-steel lining, rebuild(2) existing 24” ARV and fill the line.

Installing of the pipe was done on UPPRR right away which required a full time flagger. Slide rail system was use in the excavation of the 42” pipe and backfill with soil cement. Excavation depth for the 42” pipe was 16’

This project consisted of working along a 4 mile long transmission pipeline appurtenances at 42 sites and videotaping the entire pipeline within 20 calendar day shutdown. Work also included the installation of a 17 by 12 foot cast in place vault around a 42” and 20” pipe. The vault was 20 feet deep with high ground water.
